The EK/PBR 420SR 14/47 chain kit from EK CHAIN is designed to equip the transmission of small urban motorcycles. The SR series focuses on a heat treatment of the plates that optimizes mechanical strength and helps maintain the flexibility of the chain even after prolonged use. Ideal for daily commutes in the city, this kit combines a standard sprocket and crown for a simple and effective replacement.
This kit is aimed at riders looking for a robust and easy-to-install part for chain replacement on their urban road machines. The standard mounting facilitates intervention and tension adjustment; regular lubrication and wear checks will extend the lifespan of the drivetrain.
